I am in the process of finishing my guide book for the Sony DSC-RX10 IV camera, which I hope to have published by mid-December. Today I checked to see how well the camera does at taking infrared photos using a Hoya R72 infrared filter. (The camera uses a 72mm filter, by the way, coincidentally the same number as the filter number.)
Of course, the camera is not designed for infrared photography, so you need to use long shutter speeds to let enough infrared light in through the dark red filter. So, this type of photography is really only suited for stationary subjects such as landscapes. It works best with green trees, grass, and the like, along with blue skies and clouds. But my tests showed that the camera can take this sort of infrared photograph. I am posting an example here, which is also included in my upcoming book. This image was taken in Manual exposure mode with a shutter speed of 4 seconds at f/5.6 and ISO manually set at 1250.
